I just noticed, about 45 min ago, that I have small blisters on both of my eyes. Same location on both of them as well. To the inside of my irisis. It appears to be under just the clear layer of my eye. Is is accompanied by a yelowish streak running from the corner of my eye, across the blistered area, and just slightly past. Again this is only to the corner of my eye in relation to my nose. I'm also noticing a slight pressure on my eyes. Feels like the tops of my eyes around my forhead area are being pressed upon, but only very slightly. What might cause such symptoms?
